Referring to Fig. 1, numeral I indicates a fragmentary portion of the building wall enclosing a window opening 2 into which is incorporated the preferred form of window frame 3 movably mounting upper and lower window sashes 4 and 5 respectively. The window opening 2 encloses two window frames 3 but, as both windows have duplicate construction, only one of these windows will be described in detail. The window frame 3, Figs. 1, 3 and 4, is composed of side jamb members 6 and 1 connected by header and sill members 8 and 9 respectively. It will be noted from these figures that members 6, 1 and 9 are identical in cross-section and that header mem-. ber 8 is modified in cross-section for reasons which will be apparent hereinafter. frame members 6, 1 and 9 are substantially I-beam in construction and may be extruded in one piece, having a back 10, inside and outside outwardly directed flanges H and I2 respectively, so as to form an outwardly facing channel, and inwardly extending flanges l3 and I4 to form an inwardly facing channel, flange l3 being longer than flange M. The outwardly facing channel portions of the members 6, 1 and 9 are secured into the window opening 2 by metal angle bars l5. The header member 8 comprises substantially an outwardly facing channel having a back IS with outwardly extending inside and outside flanges l1 and I8 respectively. An inwardly ex-' tending outside flange i9 is formed on back IS. The header 3 is secured to the building opening by an angle plate 20 having an angular offset 20a. The angles l5 and 20 which surround four sides of the window frame, and as stated, serve to secure the frame in the building wall, are preferably welded together 'at their corners whereby a strong and rigid supporting mounting frame is provided. Caulking material 2| serves to seal the entire window frame in position in the window opening.

Each inwardly facing channel portion of the' frame members 6, 1 and 9 is so shaped as to house or imprison a V-shaped weather strip 22. Each back III of the above frame members carries an integrally formed rib 23 carrying a marginal lip 24, and an inwardly extending inside flange I 3 which carries an outwardly extending striking lip 25. Also formed in each back is a shoulder 26 on flange l3 and a short supporting rib 21 formed between rib 23 and flange l3. The V- shaped weather strip 22 is of resilient non-corrosive sheet material, leg 28 hearing against Window shoulder 26 and rib 21, and leg 29 hearing against striking lip 25 of the flange I3 under certain conditions, as will be mentioned hereinafter. The vertex 22' of the V-shaped weather strip is caught under the marginal lip 24 of the rib 23, and the inherent resiliency of the weather strip keeps it thus permanently imprisoned in its window frame member. The space 30 formed by the back Ill, rib 23, and rib 21 permits the weather strip to be sprung into position when the window frame is assembled.

The header member 8 of the window frame is formed with a shoulder portion 3| which serves as a striking surface or flange for the movable window sash 4. Flange 13 of member 8 and flange l4 and lip 25 of frame member 9 serve as striking portions for the window sash 5 as will be described hereinafter.

The window sashes 4 and 5 are identical in vertical cross-section, as will be seen in Fig. 3 and are also identical in horizontal cross-section as shown in the Fig. 4. They are movably mounted, one above the other, in the window frame 3 and when in closed position fall substantially within the narrow dimensions of said frame.

Each window sash has identical rail members 32, 33 and 34. The members 32 and 34, comprising the vertical members, cooperate with the frame members 6 and 1, and the lower rail member 33 cooperates in the case of window sash 5 with the sill member 9, and in the case of the upper sash 4 with the upperrail member 35 of the lower window sash 5.

As the side and lower members or rails of both sashes are identical in cross-section, it will be suflicient to describe in detail the lower member 33 of the sash 5 which cooperates with the sill member 9 of the window frame 3. This rail member is hollow and rectangular in cross-section, having a peripheral wall 36, and inner wall 31, and inside wall 38 adapted to contact with striking lip 25 of the frame member 9, outside wall 39 having a striking flange 40 adapted to strike and contact with striking flange [4 of window frame member 9. The corner 4i formed by walls 36 and 38 of this sash member is adapted to engage and flex the leg 29 of the V-shaped weather strip 22 and thereby seal the window against air and water when said sash is closed. When the sash 5 is opened, the leg 29 of the weather strip will spring and engage the lip 25 of the flange l3.

The upper sash members 35 of the sashes 4 and 5 are identical in cross-section. They may be extruded in one piece and are hollow and rectangular in section as the other sash members 32, 33, and 34 and have corresponding walls 36, 31, 38 and 33. They have an outside upwardly directed striking flange 42, and the walls 36 and 38 carry a weather strip housing arrangement which is identical with the weather strip housing arrangement of the window frame members 6, 1, and 9 and therefore carry similar part members with the exponent a added thereto.

The weather strip housing of the rail 35 is in the same vertical plane as the weather strip housing of the window frame members, thereby creating a symmetrical arrangement, It will be observed also that the hollow rectangular portions of window sashes are also in perfect vertical alignment.

The meeting rails 33 and 35, Figs. 3 and 6, of the upper and lower window sashes bring about a meeting and sealing of the window by having outside flange 40 of the sash member 33 contact outside andupwardly directed flange 42 of the sash rail 35, and by having wall 38 strike lip 25a and by having'corner 4| flex weather strip leg 29a. The -leader 8 of the window frame 3 and the sash rail 35 of the sash 4 seal and close the window'in like manner.

The window sashes 4 and 5, Figs. 1 and 2, carry window panes 44 separated by horizontal and vertical muntins 45. The rail members of both sashes carry inwardly directed flanges 46 to be engaged by window panes 44 and carry inwardly turned undercut narrow outside flanges 41 which serve to aid in holding the putty 48 in position.

The window sashes are so articulated to the window frame that the upper end of each sash partakes of a downward vertical movement and the lower end of the sash swings outwardly, upwardly and then inwardly on a curve 49 as shown in Fig. 2. This curve describes the complete reversal of a sash member so that the inner face of it is now turned outward. A preferred mechanism for producing this movement is as follows:

Mounted on the outside of window frame members 6 and I are-channel track members 50 and These channel members have their open sides facing each other and extend vertically the entire length of the window frame 3. The upper side ends of each window sash securely carry a pair of bearing blocks 52 (Figs. 1, 2, 4 and 6) which pivotally house stud shafts 53 of shoes 54 which are adapted to slide snugly up and down in the channel tracks 50 and 5|. Each channel member has inwardly turned lips 55 in order more completely to house and guide its shoe 54 and to add rigidity to the channel. Each shoe is bifurcated, as shown in Fig. 14, to form leg portions 56 and 51 capable of being sprung slightly apart and adapted to bear against channel flanges 58 and 59 respectively. The space between the leg portions 56 and'51 houses a bowed spring 60 which is adapted to exert pressure tending toforce the legs 56 and 5'! apart and into frictional engagement with their respective channel track flanges 58 and 49. In this way a frictional drag is placed upon the window sash suflicient to hold it in any of its open or reverse positions. To adjust the friction produced by the pressure of the spring, a set screw 6i threaded into leg 51 of the shoe 54 bearing against the spring 58 is provided. To get at the screw M, the guide channels have outside holes 62 which coincide with the closed position of the window sash and its brake shoe.

Each brake shoe is provided with a'housing plate 63 having ends64 and 65 bent at right angles to engage the top and bottom of the shoes. This plate 63 prevents the accumulation of dust and dirt in the bifurcated brake shoe and covers and retainsthe spring to be described. To produce friction, each bearing block 52 housesv a compression spring 61 which is adapted to press against the end of stud shaft 53 so as to cause the brake shoe 54 to exert lateral pressure against the back 66 of its channel. The other end of the spring 61 bears against an adjustable screw 68 by means of which the lateral pressure of the spring 61 may be adjusted. Fig. 16 shows a modified form of brake shoe construction in which the bolt spring 80 has been omitted and in which the screw it tends directly to force apart the legs H and 12 of the brake shoe in order to produce the necessary retardingfriction.

From the above it will therefore be understood that the upper end of each sash partakes of a vertical up and down movement and the friction drag of shoes 54 serves to counteract the force of gravity. To cause the lower end of each sash,

to describe'the curve 49 shown in Fig. 2, a pair of stay bars 13' are provided. These stay bars, Figs. 2, 4, 5, and 6, are pivoted at their lower ends on pivot screw bolts 14 secured in the side window frame members 6 and] in line with the bottom of the connected sash and their upper ends pivotallyseeured by screws 15 to the sash side rails. These stays have a length slightly more than one-half the height of a window sash so as to produce the curve shown in Fig. 2.

Each stay bar, when its window sash is closed, is housed between the back In of the side window frame member, wall 36 of the vertical window sash member 32, flange 43 of the window sash member 32, and rib 23 of the backing [0 of the vertical window frame member (see Figs. 4 and 5). It will be observed that striking flanges 48 are long enough to span the spaces occupied by the stay bars and engage the flanges l2.

By means of this arrangement, the two stay bars of each window sash are not visible when the window is closed and thereby produce a very neat appearance from both the outside and inside of the window. It is further apparent that there is sufficient space between the flange 23 and the flange H to provide for concealment of the stays I3 without interfering with the sealing contact between the rail and the resilient tongue 22 of the weather sealing member, so that when the window is closed the weather sealing member provides for resilient contact on all sides of the window and the frame in addition to the contact made between the flanges of the frame and the sash rail respectively.

To prevent each stay-bars 13 from hearing against either the wall 36 of the window sash member or backing III of the window frame member when the window sash is moved, a thin washer I6 is interposed between stay rod 13 and the wall 36 at the pivot bolt 15, and a like'washer may be interposed between the stay rod 73 and the backing I 0 at the lower pivot bolt 14. Each bolt 15, Figs. 5 and 6, is countersunk at I8 in its bar 13, and is shouldered at I9 to bear against the wall 36 and is threaded into a block which has been inserted into the rectangular frame member 32 of the window sash. The pivot bolt 14 is secured in the same way to the window frame member Ill and is threaded into one of the window frame supports I5 as shown in dotted lines in Fig. 5. In order to permit the movementof the staybars 13 the inwardly directed outside flanges B4 of side members 6 and! are cut away at Ida, Figs. 4 and 6.

When the transverse friction pressure of the springs 6i is adjusted, both adjusting screws 68 should be turned through equal angular increments in order to keep the window sash side members properly spaced from the window frame members so that the stay rods will move freely between them without scraping.

With a window sash mounted as described the upper end of the same moves down and the lower end moves out to open the window and vice versa. When the upper end of the window moves down its track the full distance as determined by the length of its stay bars 13, the lower end of the sash describes the curve 49 shown in Fig. 2 bringing about a complete reversal of the window sash as shown in dotted lines, the partially open ventilating position of window sashes 4 and being shown in full lines. The frictional drag provided by the shoes 54 in guide tracks 00 and SI will arrest the window'sash into whatever position it may be moved.

when the lower window sash 0 has been fully reversed as shown in Fig. 2, it will be noted that its rail 33 overlaps the lower end of said upper window sash 4. Therefore, it will be necessary to move the lower sash out of the path of the upper sash so that the samemay be moved to the desired position.

It will be noted from Figs. 2, 3 and 6 that due to the position of the sliding pivot point of each of the window sashes the upper contacting flanges and lips of each window sash strike their cooperating members from the inside of the room, and that the contacting flanges and surfaces of the lower members of each sash strike their cooperating members from outside the room, therefore, in order to lock collectively and individually the sashes 4 and 0 in closed position, a new and improved type of window latch particularly adaptable to the manner in which these window sashes move is provided. One latch serves to lock the meeting rails 33 and 35 of the window sashes and the other latch serves to lock the lower sash rail 33 of the window sash to the sill member 9 of the window frame 3.

This latch, Figs. 3 and 10, comprises a fixed member 02 secured to the window sash 5 and a pivoted coacting member 03 secured to the sash 4. The fixed member comprises a body portion 04 secured to the flange Ila of the rail member 35, having an inwardly extending portion 85 terminating in a vertical upstanding locking finger 06. This finger is slightly resilient and has an enlarged tip 01. The finger extends above the upper edge of its window sash 5 and is adapted to be engaged by the movable locking member 93. This movable locking member comprises a horizontal locking body portion 00 which is bifurcated to form two arms 09 which embrace a bearing bracket 90 to which the arms are pivoted by means of a shaft 9|. The locking portion 00 of the movable locking member 03 is adapted to be forced over the enlarged portion 01 of the locking finger 06 and to engage the face of said finger. The inner end of the locking member 83 terminates in an eye-ring 92 by means of which the locking member 03 may be raised or lowered into and out of locking position.

The cooperating locking parts 02 and 03 are so proportioned that only a slight-flexing of finger 86 is necessary to permit the looking or unlocking of the latching parts. The raised posi-- tion of latch member 03 is limited by a stop 93 carried on the arms 09 and adapted to engage the wall 38 of the meeting rail 33 of the sash 4.

As shown in Fig. 3, the latch above described is in locked position, thereby preventing either of said sashes 4 and 5 from opening, and the lower sash 5 is locked in closed position by a similer latch .mechanism, wherein the fixed member 82 is secured to the flange I3 of the window frame member 9 and the movable member 83 carried by the sash member 33 of the lower sash 5.

Figs. 17 to 20, inclusive, show a modified form of the window sash locking mechanism in which a fixed member 02a is mounted upon the upper rail member 33a of a lower window sash in which a movable cooperating member 83a is pivotally carried on rail 35 of an upper sash. The fixed to provide the required locking pressure.

to be engaged by a pair of arms 00a which are connected by a hand-bail 92a and are pivotally carried in a bracket 90a secured to the upper sash. The bracket 00a has spaced ears 00a which pivotally support stud shafts 9Ia formed on the arms 08a of the pivotal locking member 83a. This pivoted locking member 03a carries locking cam portions 01a which are adapted to engage and look over the fingers 00a of the fixed locking member 82a. The co-acting latching members are so proportioned that only a slight resiliency of the fingers 00a is necessary in order In other respects this modified latching form acts in the same way as the preferred form and, in addition, the modified form provides a more convenient hand grip in the form of the hand-bail Fig. 1 shows a window opening which incorporates two window frames 3 which are spaced apart by a mullion 94 which is shown in Fig. 4. The mullion 94 comprises a heavy sheet metal member bent into channel shape and includes legs 99 and oifset parallel portions 91. The parallel portions 91 are secured to the adjacent window frame lamb members I and 0 and the legs 96 are snugly engaged by flanges II of these same window frame members so as to give a neat inside appearance to the adjacent window frame members and mullion 94. The outside flanges I2 of the window frame members I and 6 are connected by an extruded metal filler plate which has grooves 99 engaged by the ends of the flanges I2. This filler plate 90 thereby gives a neat outside appearance to the mullion and is also weather proof.

In Fig. 6 is shown screwless glazing bead 44a which may preferably be applied to any form of the invention to guard the putty from deterioration, and also partially to support the pane 44. A glazing bead such as is shown in our United States Patent No. 2,119,685 may be used.

The modified form of window shown in Figs. 7, 8, 9, 11, 12, and 13 comprises a window frame I00 consisting of header IOI, vertical jamb'members I02 and I03 and sill member I04. Each window frame I00 is adapted movably to support a plurality of vertically arranged window sashes; four sashes I05, I06, I01 and I00 being shown for purposes of illustration. As the cross-section of all of the members which make up the frame I00 is identical, it will suflice to describe in detail the sill member I04.

This member, Fig. 8, is substantially I-shaped in construction, having a back I09 and inside and outside flanges H0 and I I I forming an outwardly facing channel. and inwardly directed flanges I I2 and H3 forming an inwardly facing channel. The window frame I00 is secured in the window opening by angles I00a, which may be secured together at their corners to form, as in the preferred embodiment, a rigid mounting frame.

7 The inside and inwardly directed flange II! is somewhat longer than the outside flange H3 and has an outwardly turned striking lip H4. The inwardly facing channel of said sill member houses a V-shaped resilient non-corrosive weather strip II5, one leg iii, of which bears against a shoulder II'I formed on the flange H2 and against a narrow rib I I0 formed on the back I09. The vertex N9 of said V-shaped weather strip engages underneath a marginal lip I20 said outside flange H3 and the other leg I2I of the sheet metal weather strip II extends diagonally so as to engage under the striking lip H4.

The space I22 permits the weather stripping to be sprung into position and imprisoned in the manner shown in Fig. 8. This'weather strip is retained in position in the same manner as the weather strip shown in Figs. 3, 4, 5 and 6, of the preferred form but is much larger as it spans the entire channel opening of its window frame member. As will be seen from Figs. 8, 9, 11, 12 and 13, all other members IOI, I02 and I03 which make up the window frame I00 carry a weather strip H5 in the same manner as has been described.

Each window sash, I05 to I08 inclusive, comprises identical side rails I23 and I24 and bottom rail I25. Window sashes I08, I01 and I08 have unidentical top rails I28. The topmost sash I05 has an upper rail I 250 which is identical in crosssection with the rails, I23, I24 and I 25.

The identical rail members I23, I24, I25 and I25a are hollow and rectangular in section and have peripheral walls I21, inside walls I28, outside walls I29, and inner walls I30 (Figs. 8, 9, 11

housed by backing I09, wall I2'I, flanges H2 and and I08 (Figs. 8 and 11), have similar rectangular bodies. Each peripheral wall I2Ia carries a weather strip and weather strip housing similar to that of the member I04 of the window frame and accordingly similar parts have similar references with exponent 1; added. Therefore, when the cooperating rail pairs I25 and I 26 of the sashes I08, I01, I08 meet flanges I3I strike flanges II3a, flanges I32, strike lips H and the same flanges flex weather strip leg I 2Ia (Fig. 8)

The inner walls I30 carry panes I30a by means of flanges I30!) and I300 as is well known in the art.

' in which the sashes close.

The upper ends (Figs. 8, 9, 11 and 12) of each sash are supported in the same manner as the sashes 4 and 5 of the preferred form, that is by being pivoted to blocks 50 running in tracks 5i except that the tracks are shorter. Accordingly similar parts have similar reference numbers. However, in the modifled form the guide tracks 50 and 5i are mounted in pairs on the window frame members (Fig. 7), adjacent the upper ends of each sash. Each pair of guide tracks or channels is secured to the window frame members I02 and I03 near the upper end of its associated window sash. The lowest end of each track securely carries a stop block I36 for limiting the downward movement of the upper part of the sash (Figs. 11 and 12). Each block I38 has a drain hole I31 to prevent the accumulation of dust and dirt in the bottom of its track.

The lower ends of the sashes I05 to I 08 inclusive, move in the same manner as the sashes 4 and 5 of the preferred form and have similar mechanism for doing it. For example, sash I08 has a pair of stay bars I38, Fig. 9, which have the window sashes.

their upper ends pivotally connected by pivot bolts I39 to the side walls I21 of the side rails,

and have their lower ends only one of which is shown in Figs. 12 and 13, pivotally connected to the backings I09 01 the window frame side members by screw bolts I40. Each stay ba'r I38,

Fig. 12, is positioned between a backing I09 of a window frame member and the peripheral wall I2'I of a side sash rail. The upper pivotal bolt I39 is countersunk into the stay bar I38 and threaded into block I4I inserted into the sash rail member before it'is assembled and the stay bar is prevented from contacting wall I21 by a backing I09 and is threaded into angle I000 which fixes the window'frame in the window opening. As in the preferred form, when the sash is closed, each stay bar I38 is completely II3. The flange I32 of each side sash member is broken away at I43 (Figs. 11 and 12) to permit the movement of its stay rod I38. The weather strips H5 in the side window frame members I02 and I03 are broken into sections to make room for the pivot bolts I40, the spacing washer I44 and the plate I42. These sashes are provided with the same latches as used in the preferred form.

The sashes I05, I08, I01 and I08 are not reversible therefore their guide tracks 50-5I and stay bars I38 are shorter. However, the guide tracks stops I38 are so positioned and the stay bars so proportioned to sash and window frame that a maximum downward and outward movement of a sash is possible as shown in Fig. 11. This angle is sumcient to open the sash for ventilation and to enable the outside of its pane to be cleaned easily from the inside of the room.

The window frames I00 are mounted in pairs as shown in Fig. 7 and therefore have similar mullions 94 and 98 as described in the preferred form of our invention.

In the preferred form of the invention it is desirable to house one weather strip in each of This necessitated that the header member of the window be dissimilar from its component members, because of the manner Only four difielent unit members are necessary to make up the window frame and sashes. v

In the modified form it was found advantageous to make the window frame out of one design unit member housing a .weather strip in each section thereof. This symmetricalstructure caused the uppermost window sash to be made unidentical in part in comparison with its companion sashes. This form of invention requires only four different unit members to make up the window frame andsashes. It is further observable that in the modified form the weather strip II5 extends substantially the full width between the striking surfaces of each sash rail.

Inasmuch as this form contemplates the use of ability of metallic windows and for low cost housing.

All parts of both invention forms may be formed of non-ferrous extruded metallic units for weather resisting reasons. Aluminum alloys are desirable because they are light in weight and thus produce windows that are easily assembled, and transported and readily incorporated in buildings. .The weather strip is also preferably formed of non-ferrous springy material.

While we have illustrated and described in detail certain preferred forms of our invention, it is to be understood that changes may be made therein and the invention embodied in other structures. We do not, therefore,'desire to limit ourselves to the specific construction illustrated, but intend to cover our invention broadly in whatever form its principle may be utilized.

We claim:

1.
